Pump seat for an inflatable product

ABSTRACT

A pump seat for an inflatable product includes a hollow body with an open end. The body has a coupling portion formed at a side opposed to the open end. An opening is defined in the center of the coupling portion. A tongue is movably connected on the coupling portion for closing the opening. A finger is formed on the tongue and extends towards the interior of the hollow body. A recess is defined in the body beside the opening. A plug is selectively positioned in the opening or the recess. When an inflating process applied to the inflatable product is finished, the plug is inserted into the opening to provide a further airproof effect.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a pump seat for an inflatable product,and more particularly to a pump seat which can effectively prevent airleakage.

2. Description of Related Art

Large inflatable products made of rubber material, such as airbed orinflatable swimming pool etc., should be inflated and deflated with anelectrical pump.

The inflatable products each have a seat for mounting the electricalpump. A valve is provided in the seat for connecting with a nozzle ofthe electrical pump. The valve includes a tongue formed therein as anairproof element. During inflating process, the tongue is pusheddownwards to open the valve. When the inflating process is finished, thetongue can be returned back to close the valve to prevent air leakage.

However, the tongue may incompletely close the valve, and air in theinflatable product will leak out during use period.

Therefore, the invention provides a seat for an electrical pump tomitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a seat for anelectrical pump which can completely prevent air leakage in aninflatable product.

Other objectives, advantages and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1-3, a pump seat for an inflatable product inaccordance with the present invention includes a hollow body (10) withan open end. A coupling portion (11) is formed on a side of the hollowbody (10) opposed to the open end. An opening (12) is defined in thecenter of the coupling portion (11). A tongue (13) is movably connectedon the coupling portion (1) for closing the opening (12). A finger (14)is formed on the tongue (13) and extends towards the interior of thehollow body (10). A recess (15) is defined beside the opening (12).

A plug (20), which can be received into the opening (12) or the recess(15), has two elastic handles (21) symmetrically and pivotally connectedto the top of the plug (20). The plug (20) has a circular cross section.The elastic handles (21) can be pivoted downwards to a horizontalposition, as shown in FIGS. 1 and 3, and can be pivoted upwards to avertical position so as to conveniently remove the plug (20) from theopening (12) or the recess (15), as shown in FIGS. 2 and 4. When aninflating process to an inflatable product is finished, the plug (20) isinserted into the opening (12) to provide a further airproof effect.

During an inflating, deflating or in a non-using status, the plug (20)can be removed from the opening (12) and inserted into the recess (15),as shown in FIGS. 4 and 5. Thus, the plug (20) is stored appropriatelyand will not be lost.

With reference to FIGS. 6-7, the pump seat (10) is mounted on aninflatable product (30). During an inflating process, an electrical pump(40) is received in the hollow body (10). An inflating nozzle (41) ofthe electrical pump (40) is connected to the opening (12). Thecompressed air in the electrical pump pushes the tongue (14) downwardsto open the opening (12) for inflating the inflatable product (30). Inthis case, the plug (20) is positioned in the recess (15).

When the inflating process is finished, the inflating nozzle (41) isremoved. Under the air pressure in the inflatable product, the tongue(13) will be returned back to close the opening (12). Then, the plug(20) is removed from the recess (15) and inserted into the opening (12)to provide a further airproof effect, as shown in FIG. 8.

With reference to FIG. 9, during a deflating process, the plug (20) isremoved from the opening (12) and a deflating nozzle (42) of theelectric pump (40) is inserted into the opening (12). The finger (14) ispushed by the deflating nozzle (42) to open the opening (12), so theinflatable product (30) is deflated.

With reference to FIG. 10, an electrical pump (40) can be received inthe hollow body (10) of the pump seat when the inflating nozzle (41) isinserted into the recess (15).

With the arrangement of the plug (20), air leakage can be completelyprevented.

It is to be understood, however, that even though numerouscharacteristics and advantages of the present invention have been setforth in the foregoing description, together with details of thestructure and function of the invention, the disclosure is illustrativeonly, and changes may be made in detail, especially in matters of shape,size, and arrangement of parts within the principles of the invention tothe full extent indicated by the broad general meaning of the terms inwhich the appended claims are expressed.
